Definitions
- the present invention relates to a pro-drug consisting of a cyclic undecapeptide and its use as a medicament, intended, in particular, for the treatment of ocular pathologies.
- Cyclosporins constitute a structurally distinct class of cyclic peptides which have in common to be made up of a chain of eleven amino acids, some being atypical, either because of their configuration
- cyclosporin is meant both cyclic undeca-peptides obtained from natural sources and their analogs obtained by hemisynthesis or by total synthesis, including peptolides obtained from natural sources or their analogues obtained by hemisynthesis or by total synthesis.
- this cyclic undecapeptide comprises, there is in particular that which is in position 1, namely N-methyl- (4R) -4 - ((E) -2-butenyl) -4- methyl-L-threonine, noted MeBmt.
- This amino acid is specific to cyclosporins, the ethylenic group possibly being reduced. It has an amino group which is methylated.
- the hydroxyl group which it carries is very remarkable in the sense that it is the only group of all this cyclic undeca peptide capable of leading to chemical modifications. We can also see that it is already in a steric environment highly congested making any approach to reagent extremely delicate.
- cyclic undeca-peptides whether of natural origin or obtained by synthesis, exhibit a wide spectrum of biological activities, of which the best known are immunosuppressive, anti-inflammatory, anti-parasitic, or activities allowing counteract or decrease the resistance of cancerous tumors to other medications.
- Some of these cyclic undecapeptides have been shown to have promising anti-viral activities, in particular in the treatment of AIDS by inhibiting the replication of the human immunodeficiency virus type 1 (HIV-1).
- HIV-1 human immunodeficiency virus type 1
- dry keratoconjunctivitis also called dry eye syndrome, Sj ⁇ gren's syndrome, allergic keratoconjunctivitis, in particular, those resistant to corticosteroids, mucosynechective conjunctivitis, herpetic stromal keratitis , immune limbic keratitis, Thygeson keratitis, prevention of rejection of corneal transplants, and as an adjuvant treatment for filtering surgery.
- the cyclic undecapeptides of the cyclosporin family have a highly hydrophobic character, thereby reducing their solubility in water. This characteristic is linked to the nature of the side chain of most of their amino acids, but also to the fact that some of these amino acids have their methyl amino group, thus limiting the possible number of intermolecular hydrogen bond formation between undeca- cyclic peptide and, for example, an aqueous solubilization medium.
- one of the IV infusion preparations of Cyclosporine A commercially available under the trademark Sandimmun, consists of a microemulsion using as an excipient a polyoxyethylenated castor oil known under the name of trademark Salamophor. This preparation is stored in the form of a concentrate and must be diluted just before its administration.
- this chemical modification may consist in preparing a precursor, if possible inactive, of this pharmacologically active molecule which, once administered and under the effect of physiological conditions prevailing locally within the organism, will be chemically or enzymatically modified so that the pharmacologically active molecule is released, if possible, either at the site where its pharmacological action must occur, or in the blood which will transport this pharmacologically active molecule thus released on its site of action, this corresponding to the concept of "pro-drug".
- the precursor in question of said pharmacologically active molecule is called "pro-drug”.
- Rothbard et al. have described in patent application WO 01/13957 a method for improving the administration of pharmacologically active molecules and for allowing them to cross the dermis and the epithelial membranes consisting in grafting on these molecules, reversibly, a side chain consisting of fragments of a polyarginine chain.
- these pharmacologically active molecules there are hydrophobic molecules such as Cyclosporine A.
- Crooks et al. describe in patent application WO 00/67801 the preparation of pro-drugs of anti-inflammatory agents such as flurbiprofen in order to be able to administer them locally in contact with the eye, while this time avoiding any local irritation. They have achieved this, for a number of drugs, by introducing oxygen or poly-oxygen chains.
- Cyclosporin A to the same chemical modifications, they were only able to obtain products which they describe as being stable, in other words which do not cleave to release Cyclosporin A, whether at contact with human serum or in a phosphate buffer at pH 7.4.
- the present invention therefore aims to provide the clinician with pro-drugs of cyclic undecapeptides from the cyclosporin family, on the one hand, which can be administered within the physiological environment without having to develop galenical formulations developed, on the other hand, which can be stored, then handled and administered without having to worry in particular about the pH conditions of the surrounding medium.
- the present invention also aims to make available to the clinician pro-drugs of cyclic undecapeptides of the cyclosporin family which can be administered locally in general, and in particular on the ocular surface or on the mucous membranes. , and which can then release the pharmacologically active cyclic undeca peptide within an appropriate half-life without local irritation.
- the present invention relates to a prodrug consisting of a cyclic undeca-peptide, the peptide chain of which comprises at least one amino acid residue of general formula (I) below:
- R 5 and R 6 represent, independently of one another, a hydrogen atom, an aralkyl group, an alkyl group having from 1 to 6 carbon atoms, linear or branched;
- said amino acid residue of general formula (I) derives from a residue of N-methyl- (4R) -4 - ((E) -2-butenyl) -4 -methyl-L-threonine in which the hydroxyl group of the threonine has been suitably esterified and the pharmacologically active molecule which will be released when the prodrug is cleaved within the body will consist of a cyclic undeca peptide, the peptide chain of which comprises at least one N- residue methyl- (4R) -4 - ((E) - 2-butenyl) -4-methyl-L-threonine (MeBmt).
- said amino acid residue of general formula (I) derives from a residue of N-methyl- (4R) -4-butyl-4-methyl -L-threonine in which the hydroxyl group of threonine has been suitably esterified and the pharmacologically active molecule which will be released when the prodrug is cleaved within the body will consist of a cyclic undeca-peptide, the l the peptide chain comprises at least one N-methyl- (4R) -4-butyl) -4-methyl-L-threonine residue (Dh-MeBmt).
- said aralkyl, alkaryl, heteroalkyl, heterocyclic, alkyl-heterocyclic, heterocyclic-alkyl or preceding alkyl groups are substituted with at least one of the groups chosen from -NR 8 2) -N + R 8 3 ,
- substituents R 1 and R 3 represent a linear alkyl group having from 1 to 6 carbon atoms substituted by at least one of the groups chosen from -NR 8 2 , -N + R 8 3 , -OPO (OH) 2 or the different salified forms of these groups, each of the substituents R 8 having the above definition.
- substituents R 1 and R 3 represent a linear alkyl group having from 1 to 6 carbon atoms substituted by at least one of the groups chosen from -NR 8 2 , -N + R 8 3 , -OPO (OH) 2 or its different salified forms of these groups, each of the substituents R 8 having the above definition, the corresponding amino acid residues preferably derive:
- R 1 , R 2 and / or R 3 , R 4 forming the pairs (R 1 , R 2 ) and / or (R 3 , R 4 ) are alkyl groups having from 1 to 6 carbon atoms, they can form within each couple an alkylene chain forming with the carbon atom and the nitrogen atom which carry them a cycle. Preferably, they constitute the side chain of a proline residue.
- the substituents R 5 and R 6 cannot simultaneously represent a hydrogen atom.
- at least one of said substituents R 5 and R 6 represents an alkyl group having from 1 to 6 carbon atoms, linear or branched
- the substituent R 7 represents an aralkyl group or an alkyl group having from 1 to 6 carbon atoms, linear or branched.
- said substituents R 5 and R 6 represent, independently of one another, a hydrogen atom or a methyl group.
- said pro-drug consists of a cyclic undeca-peptide, the peptide chain of which comprises a single amino acid residue of general formula (I) and thus forms an undeca-peptide cycle with a linear sequence of ten acids.
- - T is chosen from the amino acids Ala, Abu, Nval, Val and Thr;
- R 9 representing a hydrogen atom, an alkaryl group, or an alkyl group having from 1 with 6 carbon atoms, linear or branched;
- - V represents an amino acid of general formula (NR 10 ) aa, aa being chosen from the amino acids Val, Leu, Ile, Thr, Phe, Tyr, Thr and R 10 being a linear or branched alkyl group having from 1 to 6 carbon atoms;
